Brake Servo Failure

[Emily]

Can anyone help, after a nice drive in my roadster today the brake servo has failed. When applying the brakes a hissing noise is heard and becomes very hard to stop the car. My guess is the servo has a leak, hoses have been checked and are fine. This is a marina servo I think. Can it be repaired or does anyone know where I can get a replacement. Would like to get the car back on the road ASAP so any advise would be good.

Re: Brake Servo Failure

Servo repair kits are available ...itslikely it's a seal that has perished. The standard marina servo was a parts bin item so shouldn't be too hard to get bits for

Re: Brake Servo Failure

Have removed servo and it has had it. Has any one ever fitted anything other than a Marina servo system or do I need to start searching for something suitabe.

I have a used servo sitting in the garage, removed from my 1997 Hunter (Cabrio) when I fitted the dual one.
I believe it was from a Metro ???????

Your master cylinder is probably nothing like mine, but does your servo look anything like this - if so, you're welcome to it for the cost of P & P

Re: Brake Servo Failure

Hi DC no nothing like mine, mine is definitely a Marina servo think its going to be a case of hunting the scrapyards to find something that I can fit with a little modification. Was just hoping someone had already found something that fitted to save me the trouble. Looks like I can buy a universal unit from the USA but don't seem to be available in the UK.

It's worth contacting www.powertrackbrakes.co.uk
They can usually sort you out...or at least they could last time I asked..!
The unit is a generic Girling Powerstop servo...IIRC the same was used on early Escorts & Capris.

Re: Brake Servo Failure

I'm pretty sure I have one of those sat on a shelf in the Garage... Original metro servo as supplied by Marlin. I'll take a look tonight, but if I've still got it, it's up for grabs.

A Metro Brake Servo is not a direct replacement for a Marina one, if that is what "Emily" a Marina Based YKC Roadster has.
I am not sure if there is any direct replacement out there still, which is why a refurb company might be the only option without resorting to fitting an alternative Servo and extending/shortening brake lines as required.

Re: Brake Servo Failure

Do you have any clue as to the donor for Emily?
YKC took the Roadster in 1993 so the donor could have been a 1980 or later Ital (mechanically very similar, apart from the 1.7 OHC engine and some body styling) or one of the last Marinas that would have been 13 or more years old by then. I would have expected YKC to choose as late a model as possible. WAs yours fitted with Dual or Single circuit brakes?
It might provide a few more clues, but that looks to me like a Girling Supervac to me. The Lockheed ones were generally the early 1970-1974 Marinas.

You did say that you heard a hissing noise. It is quite possible that the air seal has failed around the pushrod shaft connected to the brake lever.
I don't recommend doing it yourself, but sucking on the vacuum hose connection, perhaps with a vacuum cleaner should better locate the air leak? Worth a try?
